Thanks. The [latest] BIOS has one VGA option:
Video DAC Snoop Controls how VGA and graphics devices on the PCI or AGP
bus respond to palette register accesses.
* On - forces VGA and graphics devices to snoop VGA palette register
accesses and forward them to the ISA bus.
* Off - (the default) forces VGA and graphics devices to respond
positively to palette register accesses.
There is no hardware relief for the Dell PE300 that does not involve
modifying the mother, assuming that is possible.
I have [mostly] covered the fact that I have 1152x864 as the screen
resolution by making things smaller in KDE and setting fonts in xterm. This
system was made less useful by upgrading to FreeBSD 8. I am trying to find
out if support for multiple VGA cards is in the works and what needs to
change for that to happen.
